I have a chip that wants a specific low-frequency (38k) clock crystal,
which are somewhat hard to find and pricy. I could synthesize a 38k
clock signal, but the chip is not designed to accept an external clock -
it wants that 38k crystal and a 10pF series capacitor between two pins.
Would it be possible to trick the crystal driver into syncing to an
external clock by proper attenuation and filtering? What sort of
voltages would be present in a running oscillator like this? Am I
likely to damage the chip by experimenting?
